How Could I send only the last post ?

[Comité Oracle Madrid]

Hi,

For some reason unknown  some time ago, the e-mail send to the subscribers include the last 2 ó 3 posts, some of them old. 

Before, the correct behavior was send only the last post . Now something is wrong!!! Could someone help us?

thanks in advance for your support
